DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent N0. 724,047, dated March31, 1903.

' Application filed November 15, 1902. Serial No. 131,567. (No model.)

T at whom it may concern:

Be itknown that I, OLAF SANODEN, a citizen of the United States,residing at Leeston, in the county of Polk and State of Minnesota,

have invented a new and useful Draft-Equalizer, of which the followingis a specification.

This invention relates to improvements in draft-equalizers.

The object of the present invention is to to improve the construction ofdraft-equalizers and to provide a simple, inexpensive, and efficientdevice designed for use on vehicles and adapted to equalize the draftbetween a tongue-team and a frontor lead team. The invention consists inthe construction and novel combination and arrangement of partshereinafter fully described, illustrated in the accompanying drawings,and pointed out in the claims hereto appended. In the drawings, Figure 1is a perspective view of a. draft-equalizer constructed in accordancewith this invention. Fig. 2 is a detail sectional view illustrating themanner of fuloruming the equalizing-levers on the ends of thedoubletree.

Like numerals of reference designate corresponding parts in both figuresof the drawlngs.

1 designates a doubletree pivoted at its cen- 0 ter to the upper face ofa tongue 2 by a pin 3 in the usual manner and having its ends connectedwith singletrees 4 by means of equalizing-levers, which are alsodesigned to be connected by the means hereinafter vde- 3 5 scribed witha front or lead team. Each equalizing-lever 5 is fulcrumed between itsends at the lower face of the doubletree by means of a bolt 6 or othersuitable pivot, and the inner and outer arms ofthe equalizing-la 4o verare angularly bent in opposite directions to arrange the inner endof thelever inla plane below the tongue and the outer end of the lever in aplane above the upper face of the doubletree. The outer arm of thedouble tree is supported by a brace 7", formed by bend-.

ceive the pivot 6. The outer arms of the equalizing-levers are providedWith loops or cle'vises 9 for the reception of rings or eyes 10 of thesingletree; but the latter may be connected with the outer arms of theequalizinglevers in any other desired manner. The doubletree is providedat its upper and lower faces with wear-plates, and the pivot issupported at the lower face of the doubletree by a brace 11disposed'transversely of the said doubletree. The inner portions of theequalizing-lever are approximately L-shaped and are spaced apart toprovide an opening or space-of sufficient size to enable thedraft-equalizer to be placed on the tongue from the rear end thereof.The inner ends of the equalizing-levers are connected with a clevis 13by links 14 and 15, ar-

ranged in pairs and located at the upper and lower faces of the parts,as clearly shown in Fig. 1 of the drawings. The clevis 13 is providedwith a central opening 16 for a hook 17 or other suitable device of arope or chain 18, which is designed to extend forward to the front orlead team. The transverse equalizing-levers are adapted to oscillate onthe ends of the doubletreeand equalize the draft between the front andrear teams of a vehicle.

It will be seen. that the draft-equalizer is simple andcomparativelyinexpensive in construction, that it is strong and durable,and that it is adapted to be readily applied to and removed from avehicle.

What is claimed is 1. A draft-equalizer comprising a doubletreecentrally pivoted at the rear portion of a tongue, a pair ofequalizing-levers fulcrumed on the doubletree at opposite sides of thetongue and having their inner portions arranged in a plane below thetongue, singletrees connected with the outer arms of theequalizing-levers, a clevis connected With the inner arms of theequalizing-levers and located beneath the tongue, and means forconnecting the clevis with a lead team-substantially as described. 1 r

2. A draft-equalizer comprising a doubletree, adapted for pivotalattachment to a tongue, equalizing-levers fulcrumed on said doubletreeand having their inner and outer ends arranged respectively below andabove too the plane occupied by the tongue, singletrees connected withthe outer ends of said levers, and a clevis connected with the innerends of the levers and adapted to be connected to a lead team.

3. A draft-equalizer comprising a doubletree, equalizing-leversfulcrumed on thelower face of the donbletree and having their endsangularly bent and arranged above and bewith the donbletree, a clevislocated beneath the tongue, and links connecting the clevis with theinner ends of the levers, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aifixedmy signature in the presence of two witnesses.
